Regulated Metal Deposition (RMD™) MIG Welding Process ... - Miller
Mar 2, 2008 · Use a wire brush to clean at least 1 in. back from the edge of the joint. Use only a stainless steel wire with a high silicon content, such as a 316LSi or 308LSi . Higher silicon content helps the puddle wet out and acts as a deoxidizer. For optimum performance, use a “Tri-H” gas that’s 90 percent helium, 7.5 percent argon and 2.5 percent ...
MIG (Solid Wire) Welding Calculator - Miller
Use a triple-mix gas (Helium / Argon / CO) or spray shielding gas for stainless steels. For steel, there are two common wire types. Use an AWS classification ER70S-3 for all purpose, economical welding. Use ER70S-6 wire when more deoxidizers are needed for welding on dirty or rusty steel. Welds thinner materials (22 gauge) than flux cored wires.

Guide to Pulsed MIG Welding in Manufacturing | MillerWelds
Feb 2, 2017 · • Stainless steel — Pulsed MIG typically uses a 98% argon and 2% CO2. Gas blends should limit CO2 content to no more than 5% to prevent sensitization. Watch stickout and technique: The recommended welding techniques for pulsed MIG are similar to the techniques used for spray transfer. Maintain a stickout of 5/8 to 3/4 inch, with ...
Want To Improve Results When MIG Welding Stainless Steel?
Sep 13, 2021 · Here are seven tips for optimizing results when MIG welding stainless steel: Too much carbon in the weld when working with stainless steel affects the material’s ability to resist corrosion. Therefore, it’s important to choose a shielding gas containing less than 5% carbon dioxide. A tri-mix gas of argon, helium and carbon dioxide is ...
Solid Wire Versus Flux-Cored Wire: When to Use Them and Why
Jul 2, 2007 · Gas-shielded flux-cored wires require external shielding gas, and the slag is easy to remove. Consider using gas-shielded flux-cored wires when welding on thicker metals or in out-of-position applications. Gas-shielded flux-cored wires have a flux coating that solidifies more quickly than the molten weld material.
MIG Welding: Setting the Correct Parameters | MillerWelds
Apr 29, 2020 · The following basic MIG welding settings are for welding steel with solid wire. Joint design, position and other factors affect results and settings. When good results are achieved, record the parameters. Material thickness determines amperage. As a guideline, each .001 inch of material thickness requires 1 amp of output: .125 inch = 125 amps.
What Gas Should You Use for MIG Welding in DIY Applications?
Nov 22, 2022 · While it’s less common for the DIY user, if you’re going to get into a spray transfer mode with MIG welding (such as when you’re welding a thicker plate), a 90% argon/10% CO2 gas, or C10 gas, is a good option for that. The front panel of the Millermatic® 211 MIG welder where operators can choose a MIG process for C25 and C100 gases.
Tips for Welding Sheet Metal With MIG or TIG | MillerWelds
May 2, 2007 · When welding 304 stainless steel, ER308, ER308L and ER308LSI wires are compatible, but for welding 316L stainless, you need a 316L wire. With these materials, use a tri-mix gas — 90% helium, 8% argon and 2% CO2. To weld sheet metal with solid wires, use electrode positive (EP, or reverse polarity).
Guide to TIG Welding Basics - MillerWelds
Oct 11, 2022 · For steel and steel alloy welding, switch your amperage setting to DC TIG or DCEN. (For stick welding, switch your amperage setting to DC Stick or DCEP.) Prepare tungsten: Grind your tungsten to a point. When welding on aluminum, the tungsten will begin to form a ball. If the ball grows to the same diameter as your tungsten, repoint the tungsten.
